High-Performance Double Block & Bleed Valves – API 6D, API 6A Compliant

Velan Valve Supplier | Leading Distributor & Stockist of Premium Industrial Valves

Features & Benefits

Our modular double block and bleed (DBB) valves integrate two in-line isolation valves into a single compact body with an integrated bleed valve, ensuring the highest safety standards in critical applications. Designed to replace two separate valves, our DBB solutions reduce weight, save space, and minimize leakage risks in hazardous liquid/gas transfer systems. Ideal for offshore, oil & gas, and chemical processing, these valves feature customizable materials and advanced sealing technologies for aggressive environments.

Key Advantages:

✔ Space & Cost-Efficient – Eliminates multiple valve installations, reducing piping complexity. ✔ Enhanced Safety – Bleed valve vents trapped fluid, ensuring double isolation integrity. ✔ Leak Prevention – Minimizes fugitive emissions, meeting ISO 15848 and API 6DSS standards. ✔ Versatile Material Options – CRA overlays, hard-faced seats, and corrosion-resistant alloys.

Seat Design Options

• Soft or Metal Seated with hard-faced balls & seats for extended durability.

• Self-Relieving & Double Piston Seats – Prevents pressure buildup.

• Combination Seats – Custom configurations for severe service.
